摘要
优势关系的粗糙集模型是经典粗糙集模型的扩展。首先基于向量相似度的比较方法,在区间值信息系统中定义一种新的优势关系并分析其相关性质,进而给出基于新优势关系的属性约简方法。最后通过实例说明了该方法的有效性。
Dominance relation rough set model is the extension of classical rough set model. Based on the comparative method of vector similarity, a new dominance relation is defines in the interval valued information system and analyze its related properties. And then attribute reduction method based on the dominance relation is given. Finally, an example is given to illustrate the effectiveness of this method.
